" The inventionrelates to'improvem'ents'in warping frames in which the Warp beam is driven by frictional surface contact with a drum. Such warping frames often showthe Q 'r following twodrawbacks If the"body of warp yarn on the beam becomesuntrue owing to irregular winding-on at. the beginning or from other causes,"thef beam will jump onthe V drum intended to drive it, an'd this umping is instrumental in still further accentuat n'g the untrue shape ofjthe Thesecond drairtbackfisthat the pressure of the beam {against the drum fmust varyaccording to the quality of the warp yarn.

In order to obtain the contact pressure-re 'quired for the purposeof winding thewarp yarn onto the warpbeamwithlthe' required I ,firmness, it has hitherto been usual to employ an arrangement of levers and dead "weights which also suffices as a rule. However, the

lever andweight arrangement, cannot prevent the beam from jumping. Jumping of the beam can only be'prevented by placing into the] pathv of the displacement of the'beam caused by the increaseof its diameter, acontrolled pressure, namely a braking pressure. .Efiorts have been made to obtain thisbrak- .ing pressure by braking thej displacementof V the beam bearings caused by'the continually growing diameter of the beam, but if the braking devices on the two beam bearings are not adjusted exactly alike, one hearing will give way more readily than the other, and the result is a conical shape of the yarn body of the beam.

The present invention has for its object the elimination of this fault, this aim being arrived at by subdividing the additional contact pressure necessary for the prevention of the jumping and for the formation of a firm yarn body in such a way that one component takes over the task of preventing the jumping, and the other one that of ensuring the firm yarn body. The additional pressure to prevent the emanates from a place common to both arms H supporting the beam at either end respective such as: for instance connecting rods, toothed racks',"chains or ropes, the aforesaid shaft being braked to the extentrequired by the ad- "ditional' surface contact desired. The braking' power exerted on the shaft is therefore evenly transmitted to both beam arms by means of the arrangement mentioned." The braking powertobe exerted on the shaft can 'be generated by means of dead weights, one

or more brakes of any known'kind, preferably adjustable, spring or dead weighted, or other arrangement suitable for the purpose.

, In'Figs; 1 and 2 We show an example of the .practicalapplication of the invention in rough outlines and seen from two difierent points.

'01,,70, his thebraking device placedinto the path of the displacement of the beam and the resistance of which is intended to prevent the beam from jumping.

are the 13W0 arms supporting the beam at either end {and at the ends of which the beam is supported in. bearings. 1 is a shaft supported in the machine framing, and which is connected to the beam arms 0 by means of a pair. of flexible membersf3, (chains, ropes,belts, or the like),one end of each of which is attached tothe beam arms 0 at the'point 5, said'point 5 comprising afhook, the flexible organs being passed under pulleys 4,. and-the other ends. being wrapped onto pulleys or discs or the like fixed onshaft 1. Shaft lmay be fitted with a plate or band brake, or it may carry a drum ordisc or scroll 6 onto which the; pulley member 7 of a weight 1 or springpower store is wound. It will be observed that the resistance of shaft 1 militates against a displacement ofthewarp beam. a, the resistance being evenly distributed onboth beam arms.

To permit of an easy exchange of Warp beams, the'jshaft 1 may be fitted with a toothed wheel 10 into fwhich engages a a smaller p ni n 11 connected to a hand'wheel 7' When the fl'exible members 3 have been i detached from the hooks 5,011 the beam arm's,

they can be suspended at point 13 in order to "be ready to hand When required. For.de-'
